Abstract

A monthly field study was conducted to determine the occurrence of mosquitoes in two different mosquito catching stations such as Targwa and Kyaryatgyi villages in Taikkyi Township, Yangon Region from January to September 2018 for seven months. Outdoor cattle bait mosquitoes collection was done using WHO sucking tube from 18:00 hours to 24hours for 3 days. Anopheles mosquitoes were collected for 45 minutes in every hour on the cattle body. Collected mosquitoes were placed in catching time labeled paper cups. Next day morning species identified was done all collected mosquitoes according to different mosquito identification key. Result found that a total of 855 and 1439 Anopheles mosquitoes were collected from Targwa and Kyaryetgyi villages. Of these highest number of 441 and 783 Anopheles mosquitoes were collected in March followed by 168 and 237 in July and lowest number was found 13 in January and May in Targwa village and 19 were collected in February in Kyaryatgyi village . All total of 12 Anopheles mosquitoes species were collected in the study period or this An. vagus was found highest number 527 and 737 followed by An. barbirostris and A. aconitus 139 and 139 in Targwa and 268 and 244 in Kyaryatgyi village lowest number of An. fluviatelis, An. minimus, An. ramesii 3 numbers in Tar Gwa village and 10 An. tessallatus in Kyaryatgyi village. Anopheles vagus was found highest numbers 283 and 416 in March and 96 and 102 in July as well as followed by An. aconitus 125 and 189 in March in both villages, lowest number of Anopheles was caught in January and May in both areas. An. minimus larvae were found in rice field. In conclusion monthly occurrence of Anopheles were observed differ to different density, although same species were collected in both study sites and maim vector of An.minimus were presented in these areas, is a serious problem.
